Alumina Ceramic Plates

Alumina ceramic plate is made of aluminum oxide ceramics. Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermo couple sheath form. Alumina ceramic plates can withstand high temperature and maintain high strength and hardness. Alumina ceramic plates also have superb performances in electrical insulation, high chemical resistance, good were resistance and heat resistance, and low thermal expansion. We have various sizes of semi-finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.

Application and After-Sales Service:

Alumina ceramic plates have a wide variety of applications:
• Alumina plates are hard enough to become armor for personnel or vehicles.
• The corrosion resistivity of alumina plates makes them a great material for the chemical industry.
• Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
• Used for making parts for CVD thin films, ion implants, photolithography, and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles, and insulators.

Our alumina ceramic plates are exported to USA, Canada, Europe, and South America and Southeast Asia.
